A Missouri judge has issued a preliminary injunction to prevent the State of Missouri from enforcing 162.069.4 of the Revised Statutes of Missouri, which forbids a teacher to "establish, maintain, or use a non-work-related internet site which allows exclusive access with a current or former student." Plaintiffs, the Missouri State Teachers Association, had sued to block the law, passed last spring. The judge found that the law would have a "chilling effect" on speech. More here from Reuters.
